Why tolling I-66 is actually a good idea

Express toll lanes are coming to I-66. Some drivers accustomed to a free ride are upset at the idea, but tolls will help the highway run more smoothly and increase access for car drivers. Most importantly, they’ll improve transit.

High Occupancy Toll lanes— HOT lanes, as they’re called— allow single-driver cars to use HOV lanes in exchange for paying a toll. Carpools and buses drive for free, while cars with only one person (or sometimes two people) pay.

The toll price on HOT lanes varies based on how many cars are on the road.

The point isn’t so much to make money, but is rather to manage how many cars are using the lanes. When there’s little traffic, officials want to encourage drivers to use the lanes, so the toll is low. But when traffic rises, officials want to encourage drivers to travel some other way, so the tolls rise accordingly.

One of the biggest problems with buses is that they’re often stuck in the traffic congestion from cars. HOT lanes provide a way out. Since HOT lanes are supposed to be free-flowing, and since buses can use HOT lanes, tolls create defacto busways, giving buses a way to move along the highway at speed, even if the normal un-tolled lanes are jammed.

But buses can only benefit from HOT lanes if buses are present, and if there are enough of them to be a realistic, convenient option. Unfortunately, that’s a big “if.”

Past Virginia HOT lane projects on I-95 and the Beltway haven’t delivered the bus service planners originally promised. Officials built the HOT lanes, celebrated what they accomplished for cars, and largely forgot about buses.

Both the I-66 projects, inside and outside the Beltway, have elaborate plans for more bus service. If those plans actually happen, catching a bus to western Fairfax or Prince William County might become a much more quick and convenient possibility, with frequent all-day buses instead of only a few at rush hour.

But to ensure transit benefits actually materialize on I-66, leaders will need to lock in guaranteed transit funding as part of the deal. The days of trusting Richmond to deliver are over, after the failures on I-95 and I-495.

Part of the problem on I-95 and I-495 is that a private company helped build the toll lanes, and in exchange gets to keep toll revenue as profit. That means the private company has a vested interest in limiting transit, because everyone who takes a bus is not paying a toll.

But on I-66, at least inside the Beltway, VDOT’s plan is to operate the HOT lanes itself, without using a private company. And without a private company trying to profit, officials can reinvest toll revenue straight into transit.

That’s exactly what VDOT says they want to do. As long as they guarantee that promise with a binding legal contract, it’s a good deal for transit. Much better than if VDOT went the traditional 20th Century route and simply widened I-66, with no thought to transit at all.

HOT lanes delay widening

To be sure, without a tolling plan, pressure to widen I-66 in Arlington would mount significantly.

Arlington has long opposed any widening, arguing that wider highways ultimately result in more drivers and more congestion. Under VDOT’s current plan, widening won’t be on the table until after 2025, after the bus improvements are in place.

Without the option of tolls and transit, that widening pressure would likely overwhelm decision makers.
